Abstract
Purpose: This study was conducted to investigate the intrarater and interrater reliability of Kinovea computer program in measuring cervical range of motion in frontal plane in healthy subjects.
Subjects: Sixty-four normal physical therapy intern stu-dents (54 male and 10 female) participated in this study. Their age ranged from 20-24 years with mean (22.42±0.84) and BMI mean (28.60±1.40).
Methods: Digital camera and labtop with installed Kinovea software were used. The cervical ROM of Rt. and Lt. side bending for each participant were measured using Kinovea computer program three times by examiner (B) to detect the intrarater reliability and by three examiners (A, B and C) to detect the interrater reliability.
Results: For the intrarater reliability, the ICC between the first and second trials by Rater B for Rt. and Lt. side bending were 0.941 and 0.949. The ICC between the second and third trials were 0.974 and 0.977. The ICC between the first and third trials were 0.963 and 0.963 respectively. For the interrater reliability, the ICC between Rater A & B for Rt. and Lt. side bending were 0.981 and 0.974. The ICC between rater A & C were 0.981 and 0.978. The ICC between rater B & C were 0.990 and 0.985 respectively. Kinovea computer program had an excellent intrarater and interrater reliability in measuring cervical for Rt. and Lt. side bending range of motion at p<0.05.
Conclusion: The Kinovea software program was reliable in both intrarater and interrater reliability in measuring active cervical range of motion in frontal plane.
